upon a time there was no zero. Of course people knew if they had nothing‚ but there was no mathematical notation for it. Zero was independently invented only three times. The first recorded zero is attributed to the Babylonians in the 3rd century BC. A long period followed when no one else used a zero place holder. But then the Mayans‚ halfway around the world in Central America‚ independently invented zero in the fourth century CE. The final independent invention of zero in India was long debated

Though he owns several banks‚ Merali says one may not believe that his personal bank account balance sometimes reads zero. He discloses: “I have made a decision to give 50% of my annual earnings to charity. However‚ sometimes I exceed the limit and find I have given 100 per cent”‚ he says with a shy smile. Creating employment is the next passion for the 62- year old

Investigation of the effect of particle size distribution on the flow properties of bulk solids Abstract This paper reports from a Defra sponsored project which aims to develop a toolkit that can be used by formulators to assist in controlling the flow properties of blended or engineered powders. This paper presents the results of an investigation into the effect of the breadth of the particle size distribution on the flow function‚ bulk density and internal friction of four food grade fillers

Diffusion of Hydrochloric Acid into Different Sizes of Agar Blocks Aim: Investigating the relationship between the diffusion and the surface area to volume ratio‚ with agar and hydrochloric acid. Research Question: How does the difference in surface area to volume ratio affect the diffusion? Hypothesis: As the area to volume ratio increases‚ the time taken for a complete diffusion will also increase. Background Information: Agar is a jelly like substance and in this experiment‚ agar

Will Pearson 1 Social Problems Zero Tolerance Shouldn’t Be Tolerated In September of 1997 a nine year old boy handed out Certs Mints in class. He was subsequently suspended from school for possession and distribution of “look-alike” drugs and was interviewed by a police officer (Skiba‚ Peterson 1999). This is just one of many injustices the current zero tolerance policy has handed out since it began to be used in 1989. The origins of this policy speak loudly as to what

Zero is a unique number that means “empty space” and that which represents a number and its use for computation. It was conceived from the Hindus from India. The earliest recorded evidence was found on the Gvalior inscription‚ however‚ the zero we are accustomed to today‚ came much later. Zero has two basic uses: to mean empty space or to represent a number used for computation. It is especially important in positional notations. Positional notations‚ is a numerical system in which each position

Zero is a number and a digit used in mathematics to represent that number in numerals. Zero is not a natural number but it is the smallest whole number. There are two important uses of zero. Firstly‚ in place value number system it is used as empty place indicator. Hence‚ in this number‚ 5102‚ the positions of 5 and one are correct just because of the inclusion of zero. Five is denoting a thousandth place value. Similarly if we omit zero from 5102 that is 512‚ then 5 denote a hundredth place value
